CANDY-FULLER.

Application filed A ril 16', 1918; Serial No. 228,925.

To all'arhom it may concern:

Be it known that 1, CHARLES G. WV. Nrrz, a citizen of the United States, residing at Wauwatosa, in the county of Milwaukee and 7 chine known as acandy puller y means of which candy in the process of anufacture and, in considerable quantities may. be

kneaded, agitated, or mixed mechanically as it, grows fstifl'er and stiffer during the P I primary object of the inventionis to H e a machine of this kind having three pins" moving through a course which approximates the shape of a figure eight, which movement I find 'to be most efiicient for producingthe end desired.

A secondary object of the invention is to provide mechanism for carrying these pins which consist of two spools simultaneously and oppositely rotated .and each having three notches in its periphery, together with means for shifting the pins alternately from one spool to the other, whereby three pins may be simultaneously employed and yetnotwo successive pins will trace the figure eight in the same direction.

Other objects will be brought out in the following specification, and reference 13 made to the drawings, wherein having ears 2 at its corners whereby the Figure 1 is a plan v1ew of this device, Fig. 2 a side elevation thereof with parts in section, V

Fig. 3 a bottom plan view, Fig. 4 a section on the line 4-1 of F g. 2, Fig. 5 a perspective detail of the shifter,

and

Fig, 6 a perspective detail of the retainer..

vlYli'at might be called the base plate 1 of the framework is shown in Figs. 2 and 3 as whole structure may be supported on legs if desired, or by hangers from overhead, or might be let into an opening in a table top. The base plate 1 is shown in Flg. 2 as having bosses containing upright shafts 4 and 5, hang from the plate and contain other bearings for the lower end of these shafts.

bearings 3 for a pair of and a-yoke 6 may The latter are connected by intermeshing gears 7, and the shaft 41 is shown as having a power wheel 8 driven byv a belt 9, although rotary motion may be imparted to the shafts in any suitable way.

v Posts 10 rising from the base plate 1 carry a top plate 11, and these two plates have ample circular openings 12 concentric with the shafts on both sides respectively and intersecting at the center of the device as best seen in Fig. 1. Fixed on the shafts by suitable means such as screws through their hubs at 13 are spools 11 and'15 respectively, the upper head of each spool traveling in the openlng 12 in the top plate and the lower head in the corresponding opening inthe base plateas best seen in Fig. ,2, and each head is provided with three notches 16, 17

and 18 opening out its periphery. For convenience I have added prime marks to the notches in spool 15.

The mixing or candy pulling elements are herein shown as upright pins 26, 27, and 28, -'each of a size to enter any of the notches,

and fast on each pin is a hub 25 of a size to fit loosely between the two heads of either spool as perhaps seen best at the left of --Fig. 2. I do not wish to be limited as to the sizeor shape of the pins, as they might rise considerably higher than as shown in this view and their bodies above the structure already described might be given other configuration than that shown. Nor do I wish to be limited strictly to three pins, working in conjunction with three notches in each spool, as it is quite possible that in a larger machine a greater number of pins and notches could be used. It is the intention of my invention to provide means for causing these pins automatically to follow a course which will trace the outline of a fig ure eight, the most effectively to agitate, mix, .or pull the candy as suggested above. Two pins are shown engaging the notches in the spool 14 in Fig. 1, and two engaging the notches in the spool 15, butpne,

of each pair of pins stands in the registering notches 17 and 17 where it is about to be 32 is of crescent shape, its outer periphery being struck, on an are around the pivotal point 33, whichpointis 111 line with the in tersection between the openings 12 as best seen in Fig. 4. The head may also he provided with a slot- 34; moving over a. pin 31' to limit the rocking movement of the shifter. The outerperiphery of. the head is also by preference provided with notches 36 adapted to be engaged by the mounted tip 37 of a rethereof before it approaches the center.'

Meanwhile the intermediate pin 2? stands now at the juncture of the two notches l7 and 17 and is descending in Fig. l. It, strikes the left side of the point 31 of the shifter so that its hub pushes said point to the right while the pin is simultaneously pushed to the left into the notch .17. This rocks the shifter to the position shown and engages the pin 27 with the left spool. The latter now carries the pin downward until it strikes the left end of the head "2 of the shifter whereby the latter will of course be shifted to the left, or in other words to a position the reverse of that shown, the tip 37 of the retainer holding it in this new position and the contact. of the left cXtremity of the slot 3t with the pin 35 preventing the shifter from swinging too far to the left. The pin 2? may now pass the left end of the head, and when it reaches the position indicated in Fig. l by the notch 18 the pin has reached the position indicated by the notch 16 and the pin 26 has reached the position now shown as occupied by the pin 27; but the point 31 of the shifter now stands at the left, and therefore the hub of the pin 26 moves down the right side of this point and this pin is deflected or switched into the right spool, and into the notch 16 which is two notches behind the pin Passing down within the right hand spool, hub of the pin 28 now rocks the shifter on its pivot to restore it to the position shown in full lines in Fig. l, and by the time the pin 26 reaches the posi tion indicated at in this view, the pin 28 itself has come around to the intersecting point here shown as occupied by thepin 27 and the operation is repeated. Thus it will. be seen that the three pins acting in conjunction with the three notches arc automatically shifted from one spool to the other and caused to travel through a tortuouspath simulatin the contour of a figure eight. and meanwhile each tim a hub moves alongside thepoint 31 it will doubtless cause -the pin to rotate within the notches. of the the pin is pressed to the inner end. of the notchesit occupies in both heads of the spool by the. contact of its hub 25 ith one side of the point 31 or bf. the contact of the outer side f the pin with thew; j openings 12, and therefore no pin come displaced from either spool at any time, and the onlv time when shifting occurs is at the intermediate pointas illitetrated and described. I have found the movement imparted to the pins as just de scribed to be extremely eliicacious in mixing or pulling" candy, although l do not. wish to be limited to this specific usc of the machine.

The foregoing description and the drawings have reference to what may be considered the preferred or approved form of my invention. it is to be understood that l ma make such changes in ctmstruction and arrangement and combinatitm of parts, materials. dinamsions. et cetera. expedient and fall within the scope of the appended claims.
